The Damage Reasons for Enameled Wire

The insulation is damp. This condition is also common and generally occurs at enameled wire joints in direct buried or drained pipes. For example, if the enameled wire joint is unqualified and the joint is made under humid climatic conditions, the joint will be filled with water or mixed with water vapor. For a long time, R forms a water branch under the electric field effect, which gradually damages the insulation strength of the enameled wire and causes problems.

Chemical corrosion. The Enameled Copper Wire is directly buried in the acid-base effect area, and the enameled wire sheathing, lead skin or outer sheath is often corroded. The protective layer is chemically corroded or electrolytically corroded for a long time, causing the protective layer to fail and the insulation to drop. The enameled wire is damaged; the corrosion of the enameled wire in the unit is quite serious.

Overloaded for a long time. Overloading, because of the thermal effect of the current, the load current will cause the conductor to heat up when passing through the enameled wire. The skin effect of the charge together with the eddy current loss of the steel stern and the loss of the insulating medium will also generate additional heat, and then increase the enameled wire temperature.

Enameled wire connector is faulty. The enameled wire connector is the thinnest link in the enameled wire line, and the enameled wire connector problem caused by the direct fault of the person (poor construction) often occurs. During the process of making the enameled wire joints, the construction personnel will cause the insulation of the enameled wire head to drop if there is a joint that is not tightly crimped or insufficiently heated, and then cause the incident. Environment and temperature. The external environment and heat source where the enameled wire is located may also cause excessive enameled wire temperature, insulation breakdown, and even an explosion.

Enameled Copper Wire Yellowing Causes and Treatment Methods

In a sense, the Enameled Copper Wire manufacturing industry is a material finishing and assembly industry. First, the amount of materials is huge, the cost of materials in cable products accounts for 80-90% of the total cost of manufacturing; second, the types and varieties of materials used are very high, and the performance requirements are particularly high. For example, copper for conductors requires copper purity. Above 99.95%, some products use oxygen-free high-purity copper; third, the choice of materials will have a decisive impact on the manufacturing process, product performance and service life. Among them, the selection of copper enameled wire is especially important, and if it is slightly inadvertent, it may cause a safety accident. Below, I will sort out the reasons and treatment methods for the yellowing of copper enameled wire.

There are several reasons why Enameled Wire is yellowed:

1. The temperature of the tin furnace is too high, and the fluidity is large, which leads to excessive pinhole penetration and fast penetration of copper and tin.
2 the tin layer is too thin, copper and tin penetrate quickly
3 too much flux halogen residue, copper surface pickling is not thorough enough
4, the packaging time is too fast, the heat is not scattered, the tin furnace impurities
5. The quality of copper is not enough, too much impurities
6. The temperature level has an effect on the activity of copper atoms, and the hot days are faster than the cold days.

These problems can be solved by the following treatments:

1. Mold hole diameter > line pass +0.02mm (the purpose is very simple, the plating layer is too thin);
2. After the production, put it for about 2 hours and then repack it (purpose: internal heat dissipation);
3. Purchase a good flux, with a good flux concentration, mainly the flux affects the tin plating quality;
4. Pick a better oxygen-free copper wire.

Flat Enameled Copper Wire (Brief Introduction)

Xinyu-enameledwire is one of the prominent manufacturers and exporters of Enameled Copper Wire in the market.We manufacture Enameled Copper Wires using high quality raw materials which makes the wires extremely sturdy and shock proof.

The enamel insulation of magnet wire is formed of a chemical called polyesterimide. This is a class H insulation, as rated by the Institute of Electrical and Electronics Engineers. This is the highest possible rating, and means that the wire can withstand temperatures of 356 degrees Fahrenheit for at least 20,000 hours. This makes enameled copper wire capable of carrying more current than wires of the same size insulated with anything else.

Precautions During the Winding Process of Enameled Copper Wire

(1). The winding method is strictly carried out according to the requirements of the drawings. If it is arranged, the Enameled Wire should be arranged regularly. There should be no unevenness, looseness, crossover and knotting. If there is a winding, the enamelled wire should be kept at a certain interval. .

(2). Winding winding sequence, number of turns, slot in and out of the foot is strictly implemented according to the technical requirements, not in the order of inversion, multi-turn and small circle, into the wrong foot slot; the incoming and outgoing lines should be 90° right angle, not inclined Pulling; when winding the error, the wire pack needs to be taken off and retracted, and the winding machine reset is wound from the head.

(3). If there is a retaining wall in the wire package, the enameled wire will not wrap around the retaining wall.

(4). It is strictly forbidden to use the scissors and nails to push the coil to damage the patent leather; if the winding process is concerned, please pay attention to whether the enameled wire has peeling paint, blackening, scratching, etc. If found, stop using the wire and quickly stretch it. Perform a mass response.

(5). The lead wire needs to be padded with a layer of tape. The tape should be placed in the center of the enameled wire and the winding, and it should be firmly attached and positively attached.

(6). If the casing is required to be loaded at the beginning, the length of the casing extending into the wire package shall be greater than 3 mm, and the length of the extended casing shall be flush with the bottom of the frame of the frame or slightly higher than the plane of the bottom of the pin.

(7). In order to prevent the waste of the enameled wire, the length of the starting line should be 183 mm.

(8). In the winding, it is required to add shielding tape. The shielding tape should be placed in the center of the Enameled Copper Wire trough, and pay attention to the insulation at both ends. The starting and ending ends should not be in contact with the short circuit.
